Hello all, I'm building a PM#1 steam engine, and am soon going to start on the cylinder casting. When looking at the drawing, I noticed that the slots for the steam ports are 3/32 & 3/16. I do not have a slot drill or end mill in either size, however, I do have a 3mm end mill and a 5mm. Will the...

Hi there, Would anyone who has built the PM research #1 and #3 engines be able to tell me what sized taps and reamers I would need (Or their metric equivalents)

Hi there, I am currently working on a Quayle 16-16H steam engine, but I am having trouble sourcing a flywheel to fit the engine. Its a 16-bore x 16-stroke steam engine designed for making from bar stock. The drawings call for a 59mm steel flywheel. I have a cast iron flywheel a bit larger than...

If you're interested in doing a CNC conversion I've recently watch a series on a CNC conversion of a mill similar to my one from machinery house which I previously mentioned may be a good option for CNC. Here's the video series: The equivalent available in NZ is the HM48B, you'd probably want...

1. to my knowledge there isn't much difference just different names 2. you will need some software on the computer controlling the machine, and some software to make your G-code. Mach3/Mach4 or linux CNC for the controlling machine, Fusion 360 for CAD/CAM is what ild recomend 3. in most cases...

Hello, I've recently(ish) got myself a vertical mill and i want to make a quick change tool post for my lathe. Where could I find a set of plans for one? I'm looking for something about equivalent to a BXA size for a 10"x30" lathe

I haven't tested it to 120 PSI, but it said that on the water heater. it was a bit hard to measure. i tried with my round anvil micrometers but I'm not sure of how accurate the measurement is. Ill cut it up so i can measure propery

Maybe learn from his uncle and get a lathe for 15th birthday

Definitely, when he's a bit older. I showed him around the workshop recently but he was too short to reach anything, let alone see what he is doing. He was just able to move the Z-axis on the lathe.

Hello, I am thinking of building a toy steam traction engine, similar to a mamod for my nephew for one of his birthdays. I'm wondering what you think is the age where a kid could use one of them without (much) risking hurting themselves or damaging the toy.

Hi John, the wigwags are a family of simple engines that use as many interchangeable parts as possible. Here is a link to the website with the plans for the engines: https://wigwagengine.wixsite.com/wigwag and here is the link to the youtube series on the engines...

Here's my idea. A triple-expansion wobbler. pretty useless but would be quite cool. I wan thinking of making one that's based on the wig wag engines

UPDATE: I think the copper is 26 thou thick, although it is hard to tell without cutting into it

Hello, im looking at building my first boiler and had a question. i want to use hold water heater (see pictures) for the copper, its been tested to 120 PSI before and doesn't leek. I was wondering if i would be better keeping it the way it is and adding all the fittings and putting a source of...

just to clarify when I say Stuart S50 and/or Elmers #33 I mean only one at a time.

what size boiler should I make for a Stuart S50 steam engine? I want to make a coal-fired, vertical firetube, steel boiler. the engines I want to run with it are a Stuart S50 and/or elmers#33. I believe that the S50 is that larger engine (S50 is 5/8 bore, #33 is a 1/2 bore)

Hello, I'm looking at building a vertical firetube boiler similar to the one built on the channel blondihacks however, I want to do a coal-fired boiler. also, I plan to use steel instead of copper because I don't have copper money, and know how to and have the gear to weld steel. What (if...

I'm making a small model steam engine and I need something to hold the crankshaft onto the crank plate and eccentric. I know normally you would use Loctite 609 but I can't seem to buy it anywhere and the only Loctite products I can find are quite expensive for what they are, so I was wondering...
